On Thursday, when a Malaysian Airlines plane was apparently shot down over Ukraine, a Ukrainian Buk anti-aircraft missile battery was operational in the region, the Russian Defense Ministry said, contradicting Kiev’s statements.

The battery was deployed at a site from which it could have fired
a missile at the airliner, the ministry said in a statement. It
said radiation from the battery’s radar was detected by the
Russian military.

“The Russian equipment detected throughout July 17 the
activity of a Kupol radar, deployed as part of a Buk-M1 battery
near Styla [a village some 30km south of Donetsk],” the
ministry said in a statement.

The ministry said the radar could be providing tracking
information to another battery deployed in the region, which was at a firing
distance from the plane’s flight path.

Earlier Kiev said it could not have fired a missile at the
passing civilian plane because it had no Buk missile launchers
deployed in the region. At the same time the Ukrainians said
the militias had no Buk systems in their hands, according to a
statement from the country’s Prosecutor General.

After the Russian
ministry came out with the statement, Bogdan Senyk, a spokesman
for the Ukrainian Defense Ministry reiterated Kiev’s position,
saying that "anti-aircraft missiles have not been deployed
during the anti-terrorist operation ... they are all in
place."

The Malaysian Airlines flight MH17 carrying almost 300 people on
board crashed
on Thursday as it was flying over Ukraine’s Donetsk Region. The
plane was apparently shot down by a surface-to-air missile,
although both Kiev and the local militias fighting against it
deny responsibility. A flurry of condemnations and calls for a
swift
investigation followed the disaster.
